Update: Reduced design rating due to ever-tangling cable. The cable is MADE with some type of built-in twisting/tangling design flaw. Just holding the headphones in my hand, the cable wants to twist and turn and due to its material, it's never fully "straightened out" like most other headphone cables. Due to this, it's become unusable.

First off, there are counterfeit Bose IE flooding ebay like crazy, so buyers beware. It would be smart get yours from an authorized dealer. (In my case, I bought them used from a local friend who got them at best buy).

Really a horrible set of headphones for the money.
I got these way back as an upgrade from stock ipod headphones and was blown away by the bass. At the time all I wanted was bass and boy did they deliver. At the time I loved them but as my music interests grew and expanded so did my realization that I had horrible headphones.
Last year I picked up a set of AWEI ES-Q3 off...” --kitten wizard

“You can already tell if this iem is for you by looking at the pros and cons. I personally use it a lot due to the sake of convenience (rechargeable battery, noise cancelling, wireless) and it gets the job done. I might give this a five stars had it been priced $150, but every Bose overcharges. Audio quality is nothing spectacular, nor is it bad- it is acceptable. These are the best...” --Pawn
